Cepacol Dosing

For adults and children 12 years and older: take 2 lozenges (one immediately after the other), allowing each to dissolve slowly in the mouth, repeated every 4 hours as needed, not exceeding 12 lozenges in 24 hours 1.

Dosing by Age Group

Adults and Adolescents (≥12 years)

  • Dose: 2 lozenges per administration (taken consecutively)
  • Frequency: Every 4 hours as needed
  • Maximum daily dose: 12 lozenges per 24 hours
  • Administration: Allow each lozenge to dissolve slowly in the mouth 1

Children (6 to <12 years)

  • Dose: 1 lozenge per administration
  • Frequency: Every 4 hours as needed
  • Maximum daily dose: 6 lozenges per 24 hours
  • Administration: Allow lozenge to dissolve slowly in the mouth 1

Children (<6 years)

  • Contraindicated: Do not use 1

Mouthwash Formulations

For cetylpyridinium chloride (CPC) mouthwash products (when used for plaque and gingivitis control):

  • Standard concentration: 0.05% CPC
  • Dose: 15-20 mL
  • Duration: Rinse for 30 seconds
  • Frequency: Twice daily after toothbrushing 2, 3, 4

Research demonstrates that 0.05% CPC mouthwash used twice daily provides significant reductions in plaque accumulation and gingival inflammation when used as an adjunct to mechanical oral hygiene 4. The antimicrobial effects are evident after a single use and continue to improve with 14 days of consistent use 2.

Important Caveats

The lozenge formulation typically contains benzocaine (7.5 mg) as the active analgesic ingredient, with some formulations also containing dextromethorphan (5 mg) for cough suppression 1. The strict age restriction for children under 6 years is critical due to choking risk and benzocaine-related safety concerns.
